Description

Technical Field

[0001] This utility model relates to the field of ball support plate structure technology, and in particular to a circular oscillating screen ball support plate structure. Background Technology

[0002] The gyratory screen is a high-precision screening machine. It uses a vertical motor as the excitation source, and eccentric weights are installed at the upper and lower ends of the motor to convert the rotational motion of the motor into three-dimensional motion of horizontal, vertical and inclined motion. This motion is then transmitted to the screen surface, which can efficiently filter and classify various materials, and is especially suitable for screening fine materials.

[0003] Ball support plates are used in the operation of gyratory screens. However, after long-term operation, the ball support plates need to be disassembled for maintenance, cleaning, or replacement. Most existing ball support plates are fixed to the gyratory screen by fixing threads, or even by welding, which makes disassembly and installation of the ball support plates inconvenient. Therefore, a circular gyratory screen ball support plate structure is needed. Utility Model Content

[0004] The purpose of this utility model is to solve at least one of the technical problems existing in the prior art, and to provide a circular gyratory screen ball support plate structure, which can solve the problem that the ball support plate needs to be disassembled for maintenance, cleaning or replacement during long-term operation.

[0031] Please see Figure 1-5This utility model provides a technical solution: a circular oscillating screen ball support plate structure, including an installation sleeve 3, an arc-shaped sleeve 2 fixedly connected to the upper surface of the installation sleeve 3, and an arc-shaped groove 7 opened on the upper surface of the arc-shaped sleeve 2;

[0032] Among them, the inner wall of the arc groove 7 is slidably engaged with the arc plate 8, and the upper surface of the arc plate 8 is fixedly connected with the ball support plate 1.

[0033] Among them, a fixing sleeve 9 is fixedly connected to the upper surface of the ball support plate 1, the lower end of the fixing sleeve 9 extends through the lower surface of the ball support plate 1, a circular plate 11 is fixedly connected to the inner wall of the fixing sleeve 9, and a second threaded sleeve 10 is sleeved on the circular plate 11.

[0034] The inner wall of the second threaded sleeve 10 is threaded with a fixing screw 22, and the upper surface of the fixing screw 22 is fixedly connected to a protective box 12. The upper surface of the protective box 12 has two sliding grooves 14 that communicate with it, and the inner wall of the protective box 12 is fixedly connected to two guide rods 17.

[0035] Furthermore, each of the two guide rods 17 has a sliding sleeve 19 slidably sleeved on its outer surface, and each of the two guide rods 17 has a spring 18 movably sleeved on its outer surface, with the two springs 18 respectively fixedly connected to the corresponding sliding sleeve 19.

[0036] Among them, the opposite surfaces of the two left and right corresponding sliding sleeves 19 are fixedly connected to the second fixing plate 20, and the opposite surfaces of the two second fixing plates 20 are fixedly connected to the clamping plate 21.

[0037] In this case, the opposing surfaces of the two card plates 21 slide through the outer surface of the protective box 12.

[0038] Furthermore, each of the four sliding sleeves 19 has a slider 15 fixedly connected to its upper surface. The four sliders 15 slide through the inner wall of the corresponding sliding groove 14, and the upper surfaces of the two left and right corresponding sliders 15 are fixedly connected to a connecting plate 13.

[0039] Furthermore, the inner wall of the arc-shaped sleeve 2 is fixedly connected to two first fixing plates 5, which are arranged in an upper and lower cross shape.

[0042] Furthermore, when replacing the ball support plate 1, the mounting sleeve 3 is welded to the inside of the circular gyratory screen. First, the staff opens the protective cover 4, and then the staff moves the two connecting plates 13 to the opposite position by clamping them with clips. The two connecting plates 13 drive the two left and right sliding sleeves 19 to the opposite position through the slider 15 connected to them, and compress the two springs 18.

[0043] Among them, the two sliding sleeves 19 arranged on the left and right drive the second fixing plate 20 connected to them to move to the opposite position, and the two second fixing plates 20 drive the two clamping plates 21 to move to the opposite position, so that the two clamping plates 21 are respectively disengaged from the inner wall of the two fixing grooves 16.

[0044] Then, the staff rotates the protective box 12 as a whole using clamps. The protective box 12 drives the fixing screw 11 to rotate. During the rotation, the fixing screw 11 will disengage from the inner walls of the two second threaded sleeves 10 in turn.

Then the clamps can be released, and under the action of the two springs 18, the two clamping plates 21 are inserted into the two fixing grooves 16, thus completing the installation of the ball support plate 1. The overall installation process is simple and convenient, further improving the practicality of the circular gyratory screen ball support plate structure.

[0046] Working principle: When replacing the ball support plate 1, the mounting sleeve 3 is welded to the inside of the circular gyratory screen. First, the operator opens the protective cover 4, and then the operator moves the two connecting plates 13 to the opposite position by clamping them with clips. The two connecting plates 13 drive the two left and right sliding sleeves 19 to the opposite position through the slider 15 connected to them, and compress the two springs 18.

[0047] Among them, the two sliding sleeves 19 arranged on the left and right drive the second fixing plate 20 connected to them to move to the opposite position, and the two second fixing plates 20 drive the two clamping plates 21 to move to the opposite position, so that the two clamping plates 21 are respectively disengaged from the inner wall of the two fixing grooves 16.

[0048] Then, the staff rotates the protective box 12 as a whole using clamps. The protective box 12 drives the fixing screw 11 to rotate. During the rotation, the fixing screw 11 will disengage from the inner walls of the two second threaded sleeves 10 in turn. Then the staff can remove the ball support plate 1 from the arc-shaped sleeve 2. The disassembly process is simple and convenient.

[0049] When installing the ball support plate 1, the worker picks up the new ball support plate 1 as a whole, inserts the arc-shaped clamping plate 8 into the arc-shaped groove 7, and then rotates the protective box 12 as a whole using clamps. The protective box 12 drives the fixing screw 11 to rotate, so that the lower end of the fixing screw 11 enters the inner wall of the two second threaded sleeves 10 in sequence. Then the clamps can be released, and under the action of the two springs 18, the two clamping plates 21 are inserted into the two fixing grooves 16, thus completing the installation of the ball support plate 1. The overall installation process is simple and convenient.

[0050] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings.
